https://bitbucket.org/pypy/pypy/issues/2696/patch-fix-various-tests-on-freebsd

David Naylor:

Enable tests that now run on FreeBSD:
 - termios
 - pyrepl (and fix skipif on 'freebsd', instead of the more limited case 'kfreebsd')

Mark tests as xfail on FreeBSD:
 - _vmprof.test_get_profile_path

Sundry:
 - test_recompile: libc++ defines char16_t and char32_t for __cplusplus < 201103
